Each of the four erasers has a microfiber side for dry-erase ink, a shaggy side for chalk, and an internal magnet for attachment to a magnetic whiteboard. That combination suits a shared classroom or office board where people need a place to keep an eraser close at hand. A basic single-surface eraser may be simpler if you only use one writing surface, this set adds a second cleaning surface and includes four erasers. ## Pros The main advantage is versatility: the microfiber is intended for dry-erase ink, while the furry side is designed for chalk. The erasers can be used without liquid cleaner, then hand-washed in soapy water and reused. Their magnets make it possible to store them on a magnetic board rather than on a desk or in a drawer. The set is listed in green and pink. Buyer feedback is generally positive about erasing performance, magnetic attachment, and the colors. Some customers also say the erasers wash well and hold up over time. Smudging feedback is mixed, however: while some report a clean wipe, others say marker can smear or the erasers get dirty quickly. That difference is worth keeping in mind if a spotless finish is especially important. ## Quick overview This is a four-pack of magnetic microfiber shag erasers for dry-erase boards and chalk. The microfiber side is described for dry-erase ink, and the shag side for chalk. The manufacturer says they work on most painted steel, porcelain, glass, and other dry-erase surfaces. As with any eraser, the surface you plan to use matters, the set is intended for dry-erase or chalk writing, not as a general-purpose cleaner. For a practical example, a teacher could leave one eraser at a classroom board and keep the others available for shared work areas. The magnetic backing is useful where the board itself is magnetic, it also gives the eraser a designated storage spot between lessons or meetings. If your board is not magnetic, the erasing surfaces can still be used, but the built-in magnet will not provide that storage benefit. ## Care tips Hand-wash the microfiber eraser in soapy water to remove marker lint or chalk dust, then reuse it. The product is described as washable, but no specific washing-machine instructions are provided, so hand washing is the care method supported by the available information. For a board used with both chalk and marker, use the appropriate side for the writing medium and wash the eraser when buildup affects the wipe. ## Before you decide **Can these erasers be used for both chalk and dry-erase marker?** Yes. The microfiber face is intended for dry-erase ink, and the shaggy face is designed for chalk. **Do they need liquid cleaner?** The product description says they can erase without liquid cleaners. It also recommends hand-washing them with soapy water for cleaning the erasers themselves. **Will they attach to any whiteboard?** The built-in magnets are for magnetic boards. They can still be used as erasers on a nonmagnetic surface, but they will not attach to it. ## When it makes sense It makes sense if you want several reusable erasers for a classroom, home, or office and expect to switch between chalk and dry-erase writing. The two surfaces and magnetic storage are the useful distinction from a basic eraser made for only one medium. It might not be a great match if you need a confirmed smudge-free result: buyer comments are mixed on that point, and the product information does not promise one. For a single board used only with marker, a simpler single-surface eraser may be enough, this set is more relevant when having four on hand or the chalk-cleaning side matters. ## Images ![Mr. Pen MSWE04M223 Magnetic Microfiber Whiteboard Erasers, Dual-Surface 4-Pack — 1](https://www.ofertitastop.com/i/dAriXam22qUqZZe0-W8ofSB-QL-tyfsFT8JqYNDPs11nVaPvtL41xWIz4KMIJFrcy2Jm2JaJTcGyFrJCof4yqMcvonX-PEcebNXy1mAn2QvbsmCtdmE9YeZONg.jpg) ![Mr. Pen MSWE04M223 Magnetic Microfiber Whiteboard Erasers, Dual-Surface 4-Pack — 2](https://www.ofertitastop.com/i/hwW-S9Mck0iBS6JFYFzM853x5U7FTuZjqfKM3Jut20w20exjX-NncrI-jGsApmsSWoaUgl3TRsCVXnRPvusrdffv7zoDbV5uPjbZAfCYvRq38klSzl2L3r1RPQ.jpg) ![Mr. Pen MSWE04M223 Magnetic Microfiber Whiteboard Erasers, Dual-Surface 4-Pack — 3](https://www.ofertitastop.com/i/hjqlHmX7Fn8tswqklooGCGiE2IjLh7H6b0_6JJ2J79ANSAnz4k--3QmDXGB_WApgfSQC6wWmUNC8M_fmRagiQKjFUm3sz32KfG33eSqe8sfPGgy6gpQ8OpGo8Q.jpg) ![Mr. Pen MSWE04M223 Magnetic Microfiber Whiteboard Erasers, Dual-Surface 4-Pack — 4](https://www.ofertitastop.com/i/UjtASPxyzTSxvd7Dvy0d_lhNA6MyOazJ5BkxNkeOV76vIgdjxr40YM2Ct0Qg6bwSCSsTQbc7nFq1EvGo0ElTZ-evUFnwBWGvWnF7kO9tbUGMlrj5DQLjLwZxZA.jpg) ![Mr. Pen MSWE04M223 Magnetic Microfiber Whiteboard Erasers, Dual-Surface 4-Pack — 5](https://www.ofertitastop.com/i/J9R7JMkTudhRzwTrL7W_hjjyEvfiCRLmvNoSxvtIZKxopgM2AjxT95UqRCMvP6OiM4cinnp9CVyVhC58NW2weGjWXIWypc08ie31oUdjX8yUmI64Lo7exdd40A.jpg)
